[Iup-users] About IUP and Plot

. Tue, 25 Oct 2016 18:06:33 -0700

Hi,
   I notice that there are IupMglPlot(MathGL) and IupPlot(PPlot) for plotting 
in IUP.
   The IupMglPlot demos in iuptest.exe are running slowly. How?


   How about getting PLplot(http://plplot.sourceforge.net/) into IUP? 
   I'm trying to integrate them, but have no idea of this. 
   Can you give me some hints? Thanks!

   Here are codes for demo:

#include <stdlib.h>
#include <stdio.h>
#include "iup.h"

#include <math.h>
#include <string.h>
#include <ctype.h>

#include "plConfig.h"
#include "plplot.h"

#define NSIZE    101

#pragma comment(lib, "iup.lib")
#pragma comment(lib, "plplot.lib")


void FrameTest(void)
{
    Ihandle *dlg, *frame1, *frame2;

    frame1 = IupFrame
        (
        IupVbox
        (
        IupLabel("Label1"),
        IupSetAttributes(IupLabel("Label2"), "SIZE=70x"),
        IupLabel("Label3"),
        NULL
        )
        );

    frame2 = IupFrame
        (
        IupVbox
        (
        IupSetAttributes(IupLabel("Label4"), "EXPAND=HORIZONTAL"),
        IupLabel("Label5"),
        IupLabel("Label6"),
        NULL
        )
        );

    IupSetAttribute(frame1, "TITLE", "Title Text");
    IupSetAttribute(frame1, "MARGIN", "0x0");

    IupSetAttribute(frame2, "MARGIN", "0x0");
    dlg = IupDialog(IupHbox(frame1, frame2, NULL));

    IupSetAttribute(dlg, "TITLE", "IupFrame Test");
    IupSetAttribute(dlg, "MARGIN", "10x10");
    IupSetAttribute(dlg, "GAP", "5");
    IupSetAttribute(dlg, "FONTSIZE", "14");

    IupShow(dlg);
}

int main(int argc, char* argv[])
{
    PLFLT x[NSIZE], y[NSIZE];
    PLFLT xmin = 0., xmax = 1., ymin = 0., ymax = 100.;
    int   i;

    // Prepare data to be plotted.
    for (i = 0; i < NSIZE; i++)
    {
        x[i] = (PLFLT)(i) / (PLFLT)(NSIZE - 1);
        y[i] = ymax * x[i] * x[i];
    }
    
    plsdev("");  // ???

    // Initialize plplot
    plinit();
    // Create a labelled box to hold the plot.
    plenv(xmin, xmax, ymin, ymax, 0, 0);
    pllab("x", "y=100 x#u2#d", "Simple PLplot demo of a 2D line plot");
    // Plot the data that was prepared above.
    plline(NSIZE, x, y);
    // Close PLplot library
    plend();

    IupOpen(&argc, &argv);
    FrameTest();
    IupMainLoop();
    IupClose();
    return EXIT_SUCCESS;
}
